Five studies examined adults' responses to weight conservation questions which were constructed to give subjects a choice of two incorrect answers. The results showed that adults (1) acquiesced to the misleading implications of the questions; and (2) exhibited greater nonconservation in response to questions about the body than about external…

Explores developmental implications for fathers of underinvolvement in child care using Erikson's conception of adult development and his emphasis on achieving generativity. Suggests processes by which fathers may develop generativity and outlines challenges they face in achieving it. Suggests that man's involvement in child care may be crucial to…

Results of the Need for Cognition Scale for 40 older adults indicated that their levels of need were related to their performance on Piagetian tasks. Intelligence thus appears determined by attitudes as well as ability. Motivation, need, and intellectual preferences, rather than aging, may contribute to perceived decline in intellectual skills.…

Using a symbolic object such as a model as a source of information about something else requires some appreciation of the relation between the symbol and what it represents. Representational insight has been proposed as essential to success in a symbolic retrieval task in which children must use information from a hiding event in a scale model to…

To examine (a) how young adults' personal goals change as they progress from emerging to young adulthood in their university studies and immediately after and (b) the extent to which such changes are associated with the normative transitions and the life events they experience and their age, 297 university students completed the revised Personal…

Piagetian tasks have more to do with the child's ability to inhibit interference than they do with the ability to grasp their underlying logic. Here we used a chronometric paradigm with 11-year-olds, who succeed in Piaget's conservation-of-weight task, to test the role of cognitive inhibition in a priming version of this classical task. The…

The concept of "Ubuntu" has recently received a lot of attention in spite of the fact that there is no consensus about its meaning. African scholars have strived to attain a common meaning and English translation, and while they agree that it is typically and solely African, the closest some have come up with is "African humanism". A South African…

Each generation of adolescents is exposed to a wider array of stressors and environmental deficits. Use, abuse, and dependence on alcohol and other drugs greatly impairs youths' ability to develop fully, and exacerbates and compounds other biopsychosocial problems. Physiologically, the onset of secondary sex characteristics, the growth spurt,…

Three key predictions of Piaget's groupement model of middle childhood cognition were examined in the speed and time concept areas with a total of 93 children in grades 1, 2, and 3. (ED)

Assessed the relative difficulty in the utilization of oddity and matching response strategies in 144 children, ages 5-13 years. A model of matching and oddity problem-solving is presented based on the data collected. (Author/ED)

In this self-concept scale for adolescents based on Havighurst's developmental task, the person is asked to read a paragraph which explains the task and to report the way he sees and feels about his ability to achieve the task in relation to what he can do, what others do, and what it takes to be successful at the task. Response is on a scale of…

School size, age and sex of students as related to scores on the six Piagetian Developmental Thought Processes Tasks were investigated. Five hundred seventy-four students from seventh through twelfth grades were randomly selected from 25 different schools classified as small, medium, or large. Data were treated through factorial analysis of…

Many life-style decisions are often adversely influenced by prejudicial attitudes, norms, and laws about age. The relationship between ways of thinking about developmental tasks and age prejudice is discussed. (Author)

The measurement of creativity in children is discussed. (DLS)

There is controversy among researchers about the mid-life personality and value change, and whether every person undergoes a change. Considered here are possible mid-life developmental changes, and the implications they have for working with persons having vocational and other problems during this critical period. (Author)
